Sit-ups, a form of exercise. Lie on your back, put your legs together, raise your hand, contract your abdominal muscles, swing your arms forward, and quickly become a sitting position. Keep your upper body bent forward, touch your feet with your hands and bow your head. Then return to the sitting position, and so on.

Correct sit-ups are not only harmless to the body, but also have many benefits, but we need to pay attention to the correctness of the methods.

1. At ordinary times, many people do sit-ups quickly and fiercely, thinking that this is the performance of strengthening abdominal muscles. In fact, it is easy to strain the abdominal muscles. The correct way is to cross your hands on your chest and control your abdomen when sitting up. Or increase the difficulty, hold heavy objects with both hands, and increase the exercise effect.

2. When many people do sit-ups in the middle, their bodies will naturally deviate in a certain direction. This is not right, it will make the abdominal muscles move unevenly and lose their shape.

You should try to control the direction of supine, don't deviate from the straight line, and slow down to exercise the control ability of abdominal muscles. It is best to feel the movement of abdominal muscles when you get up.

Some people think that the slower you do sit-ups, the better the effect. It is helpful to slow down the speed appropriately, but the effect will be poor if the speed is too slow. The most correct speed should be to get up faster and go down slowly, and the effect is the best.

Most people do sit-ups with their hands behind their heads and their fingers crossed. This is the biggest misunderstanding of sit-ups. Such gestures will put a burden on the cervical spine. The harder you buckle your head, the greater the load.

The correct way is to put your hands on your ears, and then put them inward (probably in the middle of the back of your head and outward). Just put your hands there gently, not too hard.

Extended data:

Breathing skills when doing sit-ups;

When doing sit-ups, you should cooperate with reasonable breathing. When doing sit-ups, exhale when leaning forward and inhale when lying on your back.

However, if the whole inhalation process is completed mechanically in the supine state, it is not conducive to the completion of the action. Therefore, in order to improve the quality of movement, we must also pay attention to the skills, that is, the process of lying on your back begins to inhale, the shoulder and back instantly touch the pad and hold your breath to abdomen, and the upper body gradually rises. When the upper body is lifted to the abdomen, it will exhale quickly and bow its head forward to complete the action.
